I feel much better with small doses of oxycodone. It gets rid of the overstimulation and makes me more social. Is this dopamine? If so, how can I safely and naturally increase it? L-tyrosine can, but I have hyperadrenergic POTS, so since L-tryptophan increases norepinephrine, this would theoretically be a bad thing. Or is it? Norepinephrine in my type of POTS only goes up on standing (along with blood pressure and heart rate).
